Let’s say that in my app I have an object instance created on page 1. The user then goes to some other part of app and I want the instance to remain. How can I ‘save’ the instance? Sessions?

Yes, use a session.
Call session_start() at the beginning of your page, then store your object with something like
$_SESSION['myobject']=$myobject;The later page can access
$_SESSION['myobject']after it too calls session_start()You need to make sure that any page which uses that session has the class for the object defined or is capable of auto-loading it.
Your class can also define the magic methods __sleep and __wakeup which allow you to clean up any member variables you don’t want serializing (like resources, such as db handles). During __wakeup you can restore these.
